with Overcurrent Threshold Comparators
Pin Configuration
Pin Description
PIN NAME FUNCTION
1 IN1+
External Sense Resistor Power-Side Connection for Amplifier 1. Bias at this pin also provides the supply
voltage for amplifier 1. This pin can be left open circuit if not needed.
2 IN1- External Sense Resistor Load-Side Connection for Amplifier 1
3 OUT1 Output Voltage from Amplifier 1 Proportional to V
SENSE
. This output is clamped at 6V.
4 OUT2 Output Voltage from Amplifier 2 Proportional to V
SENSE
. This output is clamped at 6V.
5 IN2- External Sense Resistor Load-Side Connection for Amplifier 2
6 IN2+
External Sense Resistor Power-Side Connection for Amplifier 2. Bias at this pin also provides the supply
voltage for amplifier 2. This pin can be left open circuit if not needed.
7, 8, 23 N.C. No Connection. Not internally connected.
9 OC1
Overcurrent Threshold Comparator Associated with Amplifier 1. Open-drain output. This output
transitions to high impedance during an overcurrent event.
10 OC2
Overcurrent Threshold Comparator Associated with Amplifier 2. Open-drain output. This output
transitions to high impedance during an overcurrent event.
11 OC3
Overcurrent Threshold Comparator Associated with Amplifier 3. Open-drain output. This output
transitions to high impedance during an overcurrent event.
12 OC4
Overcurrent Threshold Comparator Associated with Amplifier 4. Open-drain output. This output
transitions to high impedance during an overcurrent event.
13 IN3+
External Sense Resistor Power-Side Connection for Amplifier 3. Bias at this pin also provides the supply
voltage for amplifier 3. This pin can be left open circuit if not needed.
